InSb arrays for SIRTF

摘要

Abstract: SIRTF, and other infrared space astronomy projects, require detector arrays with extremely high sensitivity. It is a goal of SIRTF to achieve background limited performance at all wavelengths. Especially critical is the spectral region around 3 $mu@m, where the zodiacal dust emission and scattering reaches a minimum, and where there are no other natural background sources, and where a cooled space telescope provides negligible background. This is a spectral region where many of the most interesting astrophysical sources can best be studied. The IRAC (infrared array camera) SIRTF experiment requires short wavelength detector arrays (2 - 5 $mu@m) that achieve background limited operation. !2
